I believe the sole purpose of the right side glass is to keep the oil companies in business.
1. i've never been able to see a damn thing through mine; and
2. it seems impervious to sealing.
[replaced my stator with the electrosport upgrade (commence flaming
) this weekend and tried sealing the sightglass again (probably the third time). i did a much better job of cleaning and allowing the sealant to set, so fingers crossed!]
